Be it known that I, JOHN L. ANDERSON, al citizen of thelUnited` States,and a resident of tlielcity. of Ogden, the c ountyof YVeber, andl theJState of Utah, have in.

vented a certain new and useful Nesting Camp Heater, of which thei'jollowing, together with the accompanying ,drawing,

forms aA full, clear, and' exact specification, whichnwill enable othersto make'and use the same.

This invention relates to a nesting ,camp

heater, and its principal objects are to'provide a heating stove forcamp use, which shall, first, be simple and sturdy in construction;second, :consistv of a minimum of 'separate parts; third,` be easily andquickly knocked down for shipment and storage; `fourth, have itsseparate parts so formed that whenknocked down7 they maybe nested tooccupy a minimum of space and not to require boxing or crating forshipment; iiith, be rugged and clean-cut in design, and have no fragileparts 'nor projections that might be broken orf in rough handling;sixth, be truly economical in the cost of manufacture; and seventh, haveits design based `on a system of duplication of parts, thereby` making.few patterns necessary and. allowing parts which are subject to thegreatest deterioration to Vbe interchanged with parts which are subjectto the least deterioration, thus equalizing the wear and obtaining the'maximum life of the partsA 'y ln construction camps, where 'contractorsare required to. furnish heat for bunk houses, tents Aor other portableor temporai-yV shelters, there exist peculiar conditionswhich theordinary types o'fLlieatingV stoves now in fthe market, signally .failto meet. When considering thesev conditions,

it may be mentioned that allv equipment' must be continually set up,taken down and moved' fromv place to plaj,e,under circum,

stances, which at the best, are unfavorable to thelasting qualities andto the efficient handling A of, the ordinary. heating stoves. Anothercondition is, that contractors find it advantageous to carry in stock atremotel points,a very complete line of repair parts for all theirequipment, so that it becomes highlyA desirable to `reduce. thefnumberof separate parts of whiclrany lpiece o fappafl ratus may becomposed, toas `ifew as possible and to use duplicates of one pattern yin asiiiany`difeient places as possible.

meet `the Yrequirements 'summarizedl in i the above stated series ofobjects of this vinvention. l 'V The present heater is preferablymadeofcast iron yand is so designed that the body.

shall consist of a plurality of separate sec-y tions, all'- identical',in general shape and size, the shapebeing preferably that of a hollowfrustuin of a' cone. the sections may ,be made from two separatepatterns, one, aV door4 section, and the other, 'a plain'section. Allthe body sections othe heater may be mounted on a base section in thedesired order, the uppermost body section being surinounted by'l a coversection, Vv'vhich latter may be rprovided withan vintegral collar` for'receiving the n.

usual smoke pipe. The various sections may be held together by ironrodsextending from thebase section lthroughthe body sec- The features ofthis invention upon which the protection of Letters Patent is desired,are collectively grouped in the appended claims. f A

Throughout the different views, similar .110 Referring. to `,theldrawing, l() lrepresents parts are designated by similannuinerals.

thebase section oin the stove, and around the circumference of the base,in its upper surface, is a rabbeted portion 11, adapted to receive thelower part of the ash-box section 12. Section 12 has the door 13 carriedby the lugs 15 and hinged in the pin 14, the lugs forming an integralpart of the section 12.' At its top, the section 12 has the inwardlyprojecting flange 16, and carries the superposed fire-bowl section 17,the latter having the downwardly projecting flange 18, which isconcentric with the flange 16 of the lower section 12, and is adapted toform a close joint between the two sections 12 and 17 Superposed on thelire-bowl section 17 is the upper middle section 12a, which is an exactduplicate of the ash-box section 12, and further, superposed on theupper middle section 12a is the top section 17a, which is an exactduplicate of the lire-bowl section 17. superposed on section 172L is thecover section 19, which has the integral collar 20 for receiving theusual stove pipe (not shown).

By referring particularly to Figs. 2, 3 and 5, it will be noticed thatthe lower parts of sections 12 and 12FL are formed into conical flangesas indicated at 21 and 21a, respectively, and that these flanges litsnugly over the upper portions of the sections below them. The coversection 19 may have the conical flange 22, which is similar to, and of.the same size as, the flanges 21 and 21-,

The various sections of the stove may be firmly clamped together by therods 23, which have their lower ends formed into countersink heads 24,the latter having their bearings in the bottom section 10, while therods extend upwardly through holes in vertical alignment with each otherin the various superposed sections. The upper ends of the rods 23 may befitted with nuts 25. The nuts 25, being located far from the corrodingaction of the fire, always have their threads in good condition and maybe readily removed.

The section 17 forms the fire-bowl of the stove, its lower part beingfitted lwith the grate 26 resting on the abutment 27. Section 128L isprovided with the fire door 13, and section 12, which forms the ash-box,is provided with the ash-door 13. y

The fire-bowl section 17 is obviously subject to a more severedeterioration from the action of the fire, than any other part of thestove, while the top body section 17V is obviously subject to a muchlesser deterioration. But the section 17 is of the identical form assection 17a, and interchangeable with it. Therefore, when a certaindegree of deterioration in the fire-bowl has been reached, where it canno longer be considered as serviceable for its original purpose, it maybe interchanged with the top body section, the latter then fo-rming apractically new lire-bowl, while the former still has a considerable useahead of it under the less severe exposure to the action of the fire.

The sections 12, 17, 12L and 17 a, all being conical in form and of thesame size, allow them to be nested as illustrated in Fig. 5. In nestingthe parts, the cover section 19 is preferably placed lowermost, whilethe sections 10, 12, 17,12eand 17a are preferably placed in consecutiveorder as shown, the

grate 26 being sandwiched between the sections 12 and 17 The lugs 15, onsections 12 and 12a, may be so placed that they do not interfere at allwith the nesting of the sections. This is clearly shown in Fig. 5. Thespace 27 (Fig. 5), inside the section 12, may be utilized as a containerfor the doors 18j-and 13a. Whennested, the various sections may befastened together for shipment,

by means of loops of wire (not sho-wn) threaded through the holes 21,10c, 12C, 17C, 12ac and 17 ac.
